Happy to.
While being a sit in, which is normally a bit better for lakes, I have been on close to 50-60 river trips with it and had not trouble with maneuverability, tracking or anything else.
On Lakes it is very stable to stand and fish from. The seats in this series is second to none for comfort. If you do a lot of coasting, then get out to fish several times on a trip the sit on can be better due to you bringing water in the boat each time you get in, so I carry a sponge. All in all I really enjoy this vessel. Plus its about 10+ pounds lighter than the Jackson sit on.
If you need more let me know. My brother has a sit in and its a Wilderness System Commander 12 also a nice unit but we have swapped before and I think the Ultimate 12 is more stable.
Good luck and maybe we'll see you on the water
